Lub distiller yog ib lub tshuab siv distillation los npaj cov dej ntshiab.Nws tuaj yeem muab faib ua ib leeg-distilled thiab ntau-distilled dej.Tom qab ib qho distillation, cov khoom tsis-volatile ntawm cov dej raug tshem tawm ntawm lub thawv, thiab cov khoom tsis hloov pauv nkag mus rau thawj feem ntawm cov dej distilled, feem ntau sau tsuas yog qhov nruab nrab, suav txog li 60%.Txhawm rau kom tau txais cov dej ntshiab dua, cov tshuaj alkaline poov tshuaj permanganate tuaj yeem muab ntxiv kom tshem tawm cov teeb meem organic thiab carbon dioxide thaum lub sijhawm distillation, thiab cov kua qaub uas tsis yog-volatile tuaj yeem ntxiv los ua ammonia uas tsis yog-volatile ammonium ntsev.Txij li cov iav muaj cov khoom me me uas tuaj yeem yaj hauv dej, quartz distillation cov hlab ntsha yuav tsum tau siv rau qhov thib ob lossis ntau qhov distillation kom tau txais cov dej ntshiab heev, thiab cov dej ntshiab yuav tsum muab cia rau hauv quartz lossis nyiaj ntim.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab distiller: cov dej hauv qhov dej yog boiled thiab tom qab ntawd tso cai rau evaporate thiab condense rau rov qab, uas siv ntau lub zog kub thiab kim heev.Lwm yam khoom uas evaporate thaum cua sov hauv cov dej siv los ua cov dej distilled, xws li phenols, benzene tebchaw, thiab txawm tias evaporable mercury, kuj condense rau hauv cov dej distilled raws li nws yog generated.Yuav kom tau txais cov dej ntshiab los yog ultra-ntshiab, yuav tsum muaj ob lossis peb qhov distillation, nrog rau lwm txoj kev ua kom huv.
Kev siv lub tshuab distiller: Hauv lub neej niaj hnub, lub luag haujlwm tseem ceeb ntawm cov dej distilled hauv kev sib raug zoo nrog cov tshuab thiab cov khoom siv hluav taws xob yog tias nws tsis yog tus coj, ua kom lub tshuab ua haujlwm ruaj khov thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv hluav taws xob.Hauv kev lag luam kws tshuaj, cov nyhuv qis-permeability ntawm cov dej distilled yog exploited.Cov dej distilled yog siv los ntxuav cov qhov txhab phais, tso cai rau cov qog hlwb uas nyob hauv lub qhov txhab kom nqus dej thiab o, tawg, lwj, tsis ua haujlwm, thiab zam cov qog loj hlob ntawm lub qhov txhab.Hauv tsev kawm ntawv chemistry thwmsim, qee qhov xav tau cov dej distilled, uas siv cov khoom ntawm cov dej distilled uas tsis yog electrolyte, tsis muaj ions, lossis impurities.Kev tsom xam tshwj xeeb yog xav tau rau cov teeb meem tshwj xeeb los txiav txim siab seb nws puas tau txais txiaj ntsig ntawm nws cov khoom tsis zoo, tsis muaj kev cuam tshuam permeability, lossis tsis muaj lwm yam ions thiab tsis muaj kev cuam tshuam.
Cov yam ntxwv ntawm lub tshuab distiller: Cov tshuaj alkaline potassium permanganate tuaj yeem muab ntxiv kom tshem tawm cov teeb meem organic thiab carbon dioxide thaum lub sijhawm distillation ib zaug, thiab cov kua qaub uas tsis yog-volatile (sulfuric acid lossis phosphoric acid) tuaj yeem muab ntxiv los ua kom ammonia uas tsis yog-volatile ammonium ntsev. .Txij li cov iav muaj cov khoom me me uas tuaj yeem yaj hauv dej, quartz distillation cov hlab ntsha yuav tsum tau siv rau qhov thib ob lossis ntau qhov distillation kom tau txais cov dej ntshiab heev, thiab cov dej ntshiab yuav tsum muab cia rau hauv quartz lossis nyiaj ntim.
